SS 904L Grade UNS N08904 Sheets is a non-stabilized low carbon high alloy austenitic stainless steel. The addition of copper to SS 904L Grade UNS N08904 Sheets gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. SS 904L Grade UNS N08904 Sheets is also highly resistant to chloride attack – both pitting / crevice corrosion and stress corrosion cracking.
SS 904L Grade UNS N08904 Sheets is non-magnetic in all conditions and has excellent weld ability and form ability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
